In a world reeling from an unusual plague, monsters lurk in the streets while terrified survivors arm themselves and roam the countryside in packs. Or perhaps something very different is happening. When a disease affects how reality is perceived, it's hard to be certain of anything.

Spence is one of the "cured" living at the Ironside rehabilitation facility. Haunted by guilt, he refuses to face the changed world until a new inmate challenges him to help her find her old crew. But if he can't tell the truth from the lies, how will he know if he has earned the redemption he dreams of? How will he know he hasn't just made things worse?
